Ram’s horn shell<br />
Mollusca – Cephalopoda<br />
The ram’s horn shell<br />
is actually the spiral internal<br />
skeleton of a small squid-like animal,<br />
Spirula spirula, that lives in the deep open<br />
ocean. The shell, divided into small gasfi<br />
lled chambers, helps the Spirula to move<br />
up to the ocean surface at night.<br />

Did you know?<br />
When the animal dies, the shell<br />
fl oats to the surface and often<br />
becomes a raft on which other<br />
creatures, such as goose<br />
barnacles, attach themselves.
